Ok so it's pretty obvious my clutch is worn. Looking for a rebuild kit for a basic 2000 v11 sport. Anyone got opinions? What additional maintenance should I do while in there? This bike has ~30Kmi on it. No current leaks or other issues but I'm open to suggestions.

Anyone else out there had this problem? - My Scura has a genuine RAM single plater, which I put in to replace the original "grenading flywheel" scura clutch, just for peace of mind. The RAM only has about 8,000 miles on it, but recently started to slip when cold, but was fine once the bike was warmed up. A quick visual check showed no sign of any oil near the clutch, and virtually no wear of the clutch plate . So I checked the slave cylinder, and what was apparent was that the piston was backed up as far as it would go in the cylinder, and so was putting pressure on the push rod and so stopping the clutch from fully engaging. I guess the reason the clutch slip went away when the engine was hot was simply due to the expansion of the castings relieving some of this pressure. As a temporary fix I put washers between the slave cylinder and the back of the gearbox, to create a bit of extra "headroom" for the piston. (Sounds easy but was a pig of a job). This has cured the problem, and I now have a fully functioning clutch again - for now. However it's only a matter of time before the problem will re-occur, as the washers are only about 1mm thick, and from the design of the clutch, I reckon it will only need the plate to wear another 0.2mm or so to take up all the extra 1mm. I suspect the problem stems from the fact that the RAM clutch was actually originally designed as a replacement for the 2 plater cable operated clutches, and so the necessary clearance between push rod and diaphragm could always be found just by adjusting the cable or the screw on the actuating arm. But with the hydraulic mechanism there is no adjuster, so no way of adjusting it that I can see, other than my bodge with washers. Unless there's something strange about my set-up, I assume others must have suffered a similar problem. If so, how did you get round it? I don't fancy having to replace the clutch every 8.000 miles, when it's hardly worn at all, so are there any other fixes other than periodically sticking more washers in to take up the wear? Shorten the push-rod? fit a different slave cylinder? Any ideas gratefully accepted!
